We then have to change xenc-schema-11.rnc as well.  Attached please find a
proposal (named xenc-schema-11-rev.rnc).

There are three changes.

1) Addition of MGF and MGFType

xenc11_MGF = element name MFG {xenc11_MFGType }
xenc11_MGFType =
  # Restricts xenc11:AlgorithmIdentifierType
  attribute Algorithm {xsd:anyURI}

2) Addition of an alternative option in xenc_EncryptionMethodOtherParams

  (attribute Algorithm { xsd:anyURI
"http://www.w3.org/2001/04/xmlenc#rsa-oaep" },
   xenc11_MGF?)

This means that when the value of the Algorithm attribute is c,
an optional MGF element can occur (after the optional KeySize element).

3) Add http://www.w3.org/2001/04/xmlenc#rsa-oaep to the list of known algorithms

This is needed so that lenient schemas do not allow other elements when
@Algorithm="http://www.w3.org/2001/04/xmlenc#rsa-oaep".
